INTEGRAL DOMAINS WITH FINITELY MANY STAR OPERATIONS OF FINITE TYPE
Let D be an integral domain and SF(D) be the set of star operations of finite type on D. We show that if |SF(D)| < ∞, then every maximal ideal of D is a t-ideal. We give an example of integrally closed quasi-local domains D in which the maximal ideal is divisorial (so a t-ideal) but |SF(D)| = ∞. We also study the integrally closed domains D with |SF (D)| ≤ 2.
